The core functionality of the tool is automated test generation of optimized test suite; the tool has extensive list of options for the same. The product's integration with other tools sets it apart. It has integrations with many upstream (for requirements mapping) and downstream (export of test cases to various tools) products. It is like "plug-and-play". 

For any customized downstream tool, like our proprietary automation framework, support is provided for custom development. It is has features - Business AD - to use in Agile implementations. The latest version seems to have support for BDD/Gherkin as well, which we have not used much. 

The tool has the ability to integrate with various requirement management, test management, and version control tools. It allows for maintaining traceability throughout the STLC.

Other than generating automation scripts tool implements algorithms to ensure 100% coverage with the optimized test set. This avoids the fear of over-testing/Under testing. Also, graphical representation helps to identify the possible requirement gaps

Reusability of exiting components helps to reduce duplicate efforts and allows to maintain project properly.

The ability to reuse existing components is very useful when we work on a project that is already started.

The reverse engineering concept, where I can convert manual test cases into the design-level and then make further use of them in the project, is very helpful.

We are able to convert existing components into other languages based on user requirements. It is very useful to migrate the scripts from one automation tool to another automation tool.

The use of external data in the model, allowing us to use it for test generation and scripts, is another valuable feature.
